This project works with the Chronos - LEGO Mindstorms EV3 clock robot. It makes the hands of the clock start moving like they would on a real clock. There are two programs in the project, one that controls hours and minutes hands, and second that controls seconds and minutes hands of the clock.

This project works with the Chronos - LEGO Mindstorms EV3 clock robot. It aims to teach you to read the clock by showing a randomly selected time and giving you 5 seconds to guess what it is. It then shows you the correct answer and returns to its starting position.

This project contains two programs. Both programs are made for Omusbot - LEGO Mindstorms EV3 sumo robot. The first one is a simple program that makes the robot spin, until it detects something with its ultrasonic sensor and then it attacks forward until it detects the black border of the sumo field, at which point it goes back two rotations. The other program is does the same thing, but it can detect also if the robot is being pushed from the back. This is achieved using behaviour programming which is explained here: How to make a behaviour program?

This program is an exemplary solution for the tasks in lesson 6 of course 4.5. It builds on the Example solution for the tasks in lesson 5 of course 4.5 program by adding conditions to observe the arithmetic order of operations and generate achievable results. To operate correctly, the robot must have a medium motor attached to port A and a touch sensor attached to port 1.

This block checks if its given number is an integer and returns a logical answer "Yes" if the number is an integer.

The way it works is by rounding down the set number and subtracting the result from its original non-rounded value. If the number was an integer, then the rounding did not change it and the result of the subtraction will be 0. If the result is different from 0, then the number was changed during its rounding, which means that it was not an integer.
